| Writeup |
Writeup from MN J6(1):
Y-790114, 81-1: Eucrite Blocky small stone with scattered fusion crusts. This breccia is dominated by large fragments of single subophitic eucrites with dark mesostasis, but very small fragments of a dark vitric clast with pyroxene phenocrysts and pyroxene fragments of fine exsolution lamellae on (001) are also present. Large pyroxene phenocrysts in a clast have fractures filled with fayalite, and lath-shaped plagioclase in crystals contain thin core of pyroxene. These features are same as those of the pristine eucrites, Y-75011, 84. | ||||||||||||||||
